Hi Christian9872,
Carbon nanotubes, in general, is a material and can be used in various product applications just like other nano materials. Using carbon nanotubes to strengthen metals is one such application. I have not heard of applications? in which nanotubes are used to strengthen fabrics, though it may be possible; however, I have heard of applications where nanotubes are used to make conductive fabrics.

Can it be worn as something like a shirt? Can it shape form like some other nano technologies? If those 2 can happen that would be the best military suit. It could be very warm and shape shift into a T-Shirt or a sweatshirt. It could deflect bullets and maybe reduce Thermal. It could be used to have super strength and speed. The possibilities are endless. Sadly humans worry to much about money. If money didn’t exist I think people would be far more advanced :P.

Hi futuramark and moonbeamxxchainsaw,
Both of the applications you mentioned are (I believe) currently being considered by various researchers in the field. Some think nanotubes would be a great material for the cable in a space elevator; others are also looking into using nanotubes to strength metals used in buildings and blades.

The gold is not currently being recycled, though it certainly could. The gold, being so thin, actually does not represent a large cost in the process (I think there was a related comment/question before somewhere; let me know if you can’t find it.)

may I ask if the gold being used in the process is recycled.

of research going on. While they may not be specific to nanotubes, they do pertain to nanotechnology. One example uses nanotechnology circuits and nano-materials to build a sensor to sense pH levels in biological systems.

If nanobots were to …
If nanobots were to exist one day, they would not likely “see” in the traditional meaning. That is, they will not have “eyes” that use visible light to see their surroundings. Instead, they will “see” via sensors that sense their environments, such as the pH level, or glucose level in blood…etc, or sense things in very close proximity, e.g. whether they are touching/attached to a red blood cell, white blood cell, or other cell types. In this regard (sensing as “seeing”), there is a lot

-nanotubes are indeed light-weight given its strength
-nanotubes, mixed in with various materials, have been shown to improve the mechanical properties of those various materials

Thank you for your …
Thank you for your opinion. While I will not speculate on this possibility, allow me to provide some related facts:
-nanotubes are one of the strongest materials known, if you normalize to it’s nano size (tensile strength is more than steel & diamonds)
-however, nanotubes in bulk, may or may not be super-strong, depending on how it is woven (or not) into a form of fiber

Instead, an …
Instead, an alternative may be to add something on the road and car tires which help them stick to each other, despite rain/snow. Or, to add something to the road which causes water to have a suppressed freezing point when it’s wetting the road. This will lead to less ice and black ice, which could help improve road conditions. However, all this is just a possibility, and may or may not materialize.

which may help the body heal (though the nanotube itself does not do the healing directly).
3. This is an interesting idea and perhaps something along these lines can be investigated. While it there are already anti-stick nano coatings today (e.g. teflon in your pots/pans, specially treated windshields…), I do not think they will be used on roads. The main reason is that if rain and water don’t stick to the road, it’s likely your car’s tires won’t either, which is very bad.

Thus, it is not unreasonable to speculate that nanotubes could be used in body armor to provide better protection due to the nanotube’s great mechanical properties (I don’t know about “deflect” though).
2. Nanotubes current have no known “healing” effects that I am aware of. Thus, I personally find it unlikely that nanotubes will be used as a medical “healer”. However, nanotube may one day be used as electrical components (circuits/batteries/sensors) in medical devices,

General questions …
General questions are very welcome.
My personal opinions to your questions (the future is always hard to predict, so I can only offer you my opinion):
1. Search “Super-thin nanotube body armor promises to stop and deflect bullets”. It is an article on nanotubes for body armor applications. While I may not agree with the entire article, I do think that nanotubes have plenty of applications besides electronics.

and one more ( i couldn’t fit it into the other comment box)
3. Could some solution be mixed into tar, or the blacktop used in roads to make ice and rain “not” stick to it?? therefore eliminating some of the worst driving conditions there are, and as a result less crashes and related deaths occuring.

okay, i have some questions..
(im not too familiar with nanotechnology and what its puposes are, or what the possibilities are.. but here we go)
1. could N.T. be incorperated into armor, along with liquid glass, to somehow further increase the protection and flexibility??
2. as with what other people said.. Could it be used as some sort of medical “healer” to speed up the process of tissue regeneration?( it sounds sci-fi ish but idk, haha)

I wonder how nanobots would “see” within the human body. I dont think any research project is being made on how nanobots would be able to see.

But, personally , I think it will be tough to do it by 2029, considering FDA approval will likely take 7+ years. Nevertheless, nanobots aside, there are plenty of other applications of nanotechnology that may and likely will reach us within the near future.
March 6th, 2010 at 4:47 am
And then perhaps …
And then perhaps some form of nano circuitry in computers/electronics and electro-mechanical systems for use in gyros and accelerometers. Of course, most of these will be improvements upon existing technologies, rather than explosive new disruptive changes; and that is partly because such improvements are more easily embraced but the market. Now, specifically regarding nanobots in our blood, I cannot speculate on if or when that may happen.
March 6th, 2010 at 4:47 am
Furthermore, for …
Furthermore, for medical equipment in the US, the law requires a very thorough FDA review process before the product can reach consumers/market. So I must admit it will be very hard to accurately predict the future roadmap for nanotechnology. However, I will say that I personally believe that nanotechnology will make its way into our lives in some form or another within the next decade. It may first take form as nanomaterials coatings.
